Maximum allowable fan wattage
- 6W or lower Output voltage
- 5-11 VDC
- 2 Allows infinite control over the fan speed The new Fan Mate variable fan speed controller gives you the best possible balance between airflow noise & cooling. The Fan Mate is connected in-line with an existing fan & means that you can raise or lower the fan speed. Where a fan is making a lot of noise due to excessive airflow this can be reduced in a controlled manner until such point as the noise becomes minimal & the airflow still adequate. The silencing effect of reducing the speed of a fan even by a small amount can be very surprising
